Is it possible to create an array with angle changed like this?
I couldn't figure out a way to do it with the array modifier but,
you can start with one, them ShiftD and move it over a bit.
Then hold ShiftR to repeat the last step a couple times.
Then turn on proportional editing and rotate the last one.
Scroll the mouse wheel to increase the effected range and you can change the falloff type of the proportional editing.
